Hot Springs Spas Highlife series or Limelight series require a teaspoon of chlorine each day as they do not circulate enough water.

Simplesilver will work in the Hotspot models as the filtration can be adjusted. 

If Spa got Heat Pump then Simple Silver is not recommended due to the reduction in flow.

  1. Too easy!! 5 Star Review

    Posted by on 12th Apr 2017

    We have used Simple Silver for 3 years now and it is amazing. I'm not sure how it can even work, but the pool stays beautiful and clear and you don't smell like a chemical factory when you step out of the spa. I'm not good at regular maintenance but I can manage changing the Simple Silver once a year!

  2. Best Spa treatment EVER! 5 Star Review

    Posted by on 8th Aug 2015

    We learnt about this spa treatment 3 years ago. We have young kids and didnt want chemicals. Sumple Silver is really as simple as it seems. We have crystal clear water for 12mths+ without doing anything.

  3. Simple silver 5 Star Review

    Posted by on 20th Apr 2015

    It sounds too good to be true, but it realY does work just install it and as long as it receives a good supply of water. All you have to do is clean your filter cartridges every week.

  4. Wouldn't use anything else 5 Star Review

    Posted by on 7th Nov 2014

    We have used Simple Silver for the last three years. It is so 'simple' to use. Once you use it the first time all you do is put the new block in the spa. No drama. Works a treat.

  5. "Simple" = Definitely 5 Star Review

    Posted by on 17th Feb 2014

    Simple Silver is definitely simple. Just chuck it in the pool and you're good to go for 12 months (just need to clean your filter regularly as normal). Best thing for us is that we're in the country and on tank water, so only having to change the spa pool's water once or twice per year is perfect.

  6. Easy Peasy 4 Star Review

    Posted by on 8th Nov 2013

    We knew we would never stick to a weekly regime of testing and adding chemicals so this was a no brainer. So far, so good. I wonder how you tell when it has run out?

  7. No nasty chemicals and no hassles 5 Star Review

    Posted by on 8th Aug 2013

    Absolutely love using simple silver. This is our second year using it. Drop in the simple silver and Swap your used filter for a clean one once a week and that's it really. Nearly every night after work my husband and I enjoy spa o'clock; a beer or wine on Friday nights. No worries, no hassles, clean water.

  8. My thoughts 5 Star Review

    Posted by on 22nd Feb 2013

    Very simple to use am happy with it so far, no complaints

  9. The best thing other than the spa itself. 5 Star Review

    Posted by on 22nd Dec 2012

    Thank you Spa Store. I was skeptical of this product and the price tag but the 60 day money back policy convinced me to try simple silver after I researched other chlorine free products. My daughter is allergic to chlorine and this has made it so she can share the spa with the rest of our family. We do not add anything else to the spa and it is crystal clear all of the time. No testing or mixing etc. It is so simple and the only issue I had was that I did not follow the circulation instructions in the beginning. Your customer service person helped me set up my spa and it is now perfect. It is the best purchase we have made for our spa.
